​​​HOUSTON - Commuting flows among the nine counties composing
the Houston metro area underscore the strong economic linkages of the region.

Every day, over half a million Houstonians, one-fifth of the
region’s workers, commute to a job in a county other than the one in which they
reside.

According to the American Community Survey’s (ACS)
County-to-County Commuting Flows study, nearly half of Houston’s suburban
workers commute daily to Harris County for their jobs.

The greatest flow of suburban workers comes from Fort Bend County,
where approximately 170,000 workers (60.4 percent of its employed residents)
travel to Harris County. Montgomery County is second highest with close to
83,000 workers (40.6 percent of its employed residents) commuting to Harris
County.

On a city level, Houston experiences a substantial influx of
daily workers as well. According to the ACS, the city’s daytime population
grows by a third due to workers commuting into the city.

Not surprisingly, Texas A&M University
Transportation Institute’s Urban Mobility Scorecard ranked Houston fourth among
U.S. urban areas in congestion costs and fifth in total delays.
